The touchpad is detected as PS/2 Generic Mouse. Installing this driver doesn't help.
After using it with this: "download that alps-dkms package and install it in /usr/src. from a terminal, navigate to /usr/src/psmouse-alps-0.10/src and then gedit alps.c in alps.c scroll down and copy the /* Dell Vostro 1400 */ line completely. In that line you will have to replace first 3 matches, that is , replace 0x73 , 0x02 , 0x50 with 0x73 , 0x03 , 0x50 . Save the file and return to the terminal. In the terminal type dkms add -m psmouse -v alps-0.10 After this, type dkms build -m psmouse -v alps-0.10 after build is complete, install it with dkms install -m psmouse -v alps-0.10 after it installs it successfully, type rmmod psmouse && modprobe psmouse This will reload your psmouse module. Next, type xinput --list to see whether it loaded successfully or not. If it shows Alps/PS2 Alps GlidePoint in the xinput , than congrats. And i bet it will show as i got it working by this!
The touchpad is recognized as GlidePoint (which is wrong) and 2-finger scrolling isn't working. (I forgot to try to disable with Fn+F3, and now I installed Ubuntu again so I'll try to fix without any modified files)
How do I enable 2-finger scrolling, and add the option to enable/disable it with Fn+F3.
I'm using Ubuntu 12.04 64bit.
